Specification of Letters Patent.

Application filed July 1, 1916. Serial No. 107,096.

To aZZ whom it may concern:

Be it known that I, HARRY I1. I-IALLIDAY, a citizen of the United States, residing at Elmira, inthe county of Chemung and State of New York, have invented new and useful Improvements in Spools, of which the following is a specification.

This invention relates to spools, the object in view being to produce an all metal spool which may be manufactured at approximately half the cost of the ordinary wooden spool now in common use in spinning mills and in other connections, at the same time producing better results in that a considerable portion of the thread which is now wasted in connection with many spools is eliminated. l

In the use of wooden spools. heretofore employed, by reason of the nature of the material employed, the spool would vary or become warped or out of shape by reason of atmospheric changes, raising the fiber of the wood and thereby causing an uneven winding of the thread or other material thereon. F urthermore,'in the handling of the spools, the heads or flanges thereof would become broken or notched thus causing one or more layers and frequently a dozen layers of the thread to be sloughed off.

The spool of this invention hereinafter particularly described is practically indestructible and always maintains its proper shape and size and may be manufactured at approximately halfthe cost of the'present wooden spools the price of which has increased more than fifty per cent. in the last few years. In addition to this, spools manufacturedin accordance with this invention may be returned for refilling as they are not subject to injury in the same manner as the ordinary 111011 use.

The spool contemplated in this invention,

in the preferred embodiment thereof, is composed of five pieces and is made up as follows. The spool comprises a body 1 of wood spools now in comtubular construction composed of sheet metal of any desired gage and split diametrically into two equal sections as indicated in Fig. 4:. Formed integrally with the body 1 are the two head flanges 2 which flare outwardly and are also of tubular construction, said flanges being also diametrically split or divided and the portions thereof formed integrally with the respective portions or sections of the body 1. Therefore, the body of the spool and the head flanges thereof together form two substantially equal members of the spool.

In connection with ,each of the head flanges 2, I employ head plates 3 each of which is outwardly dished as clearly shown in Fig. 3. Each of said'heads is substantially in the form of a disk being slightly concavo-convex in cross section and the marginal edge thereof is bent or spun as shown at 4 so as to fitaround and closely embrace and be clenched upon an annular lip 5 at the extremity of the adjacent head flange 2. In this way each head plate 3 is securely fastened to the respective head flange and serves as clamping means for holding the two diametrically split portions of the body and head flanges together. Each of the head plates 3 is furthermore punched inwardly at its center to form a.

central tubular boss 6. A central tube and head plate spreader 7 has its opposite extremities fitted over the inwardly extending tubular bosses 6 as shown in Fig. 2 thereby serving to prevent the head plates 3 from being crushed inwardly.

In addition to the clamping and holding Patented Jam-23, tent.

action of the head plates 3, the sections of the body 1 are provided along their meeting faces and upon the inner sides thereof with interlocking flanges 8 and 9 which are clenched together in the manner illustrated in Fig. 4. The body 1 is formed with an outwardly struck thread grip 10 and one or both of the head plates 3 is also formed with an outwardly struck thread grip 11. Likewise one or both of the head plates 3 is formed in the bent portion 4- thereof with a thread receiving notch 12 in order that the end portion of the thread may be passed around the margin of the head flange and head plate and engaged under the adjacent thread grip 11. The inner end of the thread is of course engaged under the thread grip 10 which is struck outwardly from the body portion 1 of the spool.

A spool constructed as hereinabove de scribed and shown is extremely rigid, capable of rough handling and usage, retains its original shape at all times, and is therefore 5 capable of being used repeatedly whereas in and preferably of a white color so that the spools may be easily washed in large quantities thereby rendering them prefectly fit for further use.

I claim v I 1.' A sheet metal spool comprising a'tubular body with flared head flanges formed integrally therewith, said body and flanges being diametrically split into two sections the body forming parts of which are pro vided at their meetmg ing flanges, outward edges with interlocky dished head plates having their outer margins bent around the edges of said head flanges and also punched inwardly to provide inwardly extending tgbular bosses, and a. centraltubularhead plate spreader fitting at its extremities around said bosses.

2. Asheet metal spool comprising a tubular body with flared head flanges formed integrally therewith, said body and flanges being diametrically split into two sections the body forming parts of which are provided at their meeting edges with interlocking flanges, outwardly dished head plates having their outer 'margins bent around the edges of said headflanges and also punched inwardly to provide inwardly extending tubular bosses, and a central tubular head plate spreader fitting at its extremities around said bosses, the body and head plates being formed with outwardly struck thread grips, and the bent margins of the head plates being cut away to form thread receiving notches.

In testimony whereof I aflix-my signature. 50
